Steamer,
Thanks for the links but I don't think either of those is with hydraulics. I translated the comments from the first video and it seems the guy used some sort of racks or maybe a motor screw-drive cause I'm not sure how well google translated it. I did find a clip of a one that is hydraulic but the guy used the whole cab, which although is impressive, I was thinking that someone did it where it was all hidden and there could be a driver etc. Here is the link
